The Fujiwa Black Unglazed 1x1 (UNG-101C) is the gold standard for safety and high-contrast detailing in aquatic design. While white tiles create the "volume" of a pool, this unglazed black porcelain provides the critical "definition"—serving as the primary choice for lane lines, step markers, and "negative edge" details in both luxury residential and Olympic-spec commercial installations.

As part of the UNGLAZED collection, this tile prioritizes structural integrity and grip over decorative shimmer.

Fujiwa Unglazed Series | Black 1" x 1" Dot-Mounted Pool Tile

Achieve maximum safety and a bold, graphic aesthetic with the Fujiwa UNG-101C. This full-body porcelain tile is engineered to withstand the harshest environments, from high-traffic commercial splash pads to deep-water pool lanes.Because it is unglazed, the deep charcoal-black color is baked through the entire tile—it will never fade, peel, or wear away, even under constant UV exposure or heavy chemical treatment.

The Dot-Mounting system is a critical upgrade for pool professionals; unlike mesh, which can act as a "bond breaker," the dots allow for 100% mortar-to-tile contact, ensuring these tiles remain submerged for decades without popping.

Key Benefits for Commercial & Residential Use

• Superior Slip Resistance: The unglazed matte texture provides a high Coefficient of Friction (COF), making it the safest option for pool steps, tanning ledges, and zero-entry slopes.

• Safety Markers: Its deep black color provides the high-contrast visibility required by code for marking the edges of steps and deep-end transitions (Safety Nosing).

• Full-Body Construction: If a tile is chipped by a heavy pool vacuum or dropped equipment, the color underneath is the same as the surface, making damage nearly invisible.

• Architectural Flexibility: The 1x1 format easily conforms to the tight curves of "Cove" transitions and circular spa spillways.

Installation & Maintenance Tips

• Mortar Choice: Use a Waterproof Polymer-Modified Thinset. While the tile is black, using a dark gray or black mortar can help prevent light-colored "bleed" in the grout joints.

• Grout Selection: * Black/Charcoal: Creates a sleek, monolithic look that is excellent at hiding algae or mineral buildup.

  • High Contrast: Pair with white unglazed tiles and white grout for a "checkered" or classic "art deco" pool bottom.

• Efflorescence & Scaling: On a black matte tile, white calcium scaling is more visible than on light tiles. Regular maintenance with a pool-safe descaler is recommended to keep the black looking deep and saturated.

• Layout: For safety "nosing" on steps, installers typically use 2 to 3 rows of these 1x1 tiles to create a clear visual boundary.

Frequently Asked Questions (FAQ)

Q: Will the black color get hot in the sun? A: If used on a dry deck or "coping" surface in direct 2026 summer sun, it will absorb more heat than white tile. However, when submerged or used as a waterline tile, the water keeps the porcelain at a comfortable temperature.

Q: Is it "stain-proof"? A: Yes. High-fired porcelain is impervious. While the surface is matte and has a slight tooth, it will not absorb oils or chemicals.

Q: Can this be used for "Lane Lines"? A: Absolutely. This is the industry-standard tile for racing lanes in competitive pools due to its durability and contrast against white or light-blue pool finishes.
